15. Brora, Sutherland. (NC 903 041)

The Government Communications Headquarters station (GCHQ) at Brora was closed in 1984. GCHQ is an intelligence and security organisation within the British security services and was officially secret until 1983. Its two main purposes are signals intelligence (sigint) and information assistance. Having previously been kept secret for over 40 years between 1939 and 1983, you can visit the GCHQ website at www.gchq.gov.uk. GCHQ has attracted some unwanted publicity in recent years as the organisation has moved into new custom built headquarters in Cheltenham. The building, shaped like a doughnut, was funded by PFI and public money and cost £337 million.
